My classmates chose martial arts and fantasy, but I chose the prehistoric world.

After sitting in seclusion for millennia, he finally emerged from the pass.

Meng Chuan pushed open the courtyard gate, and the tide of laws above Wanfa Island was still as turbulent as it had been ten thousand years ago, with a rich spiritual energy of heaven and earth rushing towards him.

He did not disturb Yan Qing and Tapa, who were immersed in their cultivation, and walked out of the courtyard alone.

Wanfa Island is very large.

Even though Meng Chuan lived here for ten thousand years, he never actually set foot on even one-tenth of the island.

Previously, he devoted himself to cultivation and spent most of his time in seclusion in the courtyard.

Now that he has slowed down and is walking on the streets of Wanfa Island, he has discovered that the island is far more prosperous than he had imagined.

The wide bluestone streets are lined with shops, some selling elixirs, some selling magical artifacts, and others buying all kinds of rare and precious materials.

The streets were bustling with people, including young men in fine clothes, elderly men with profound presence, and even alien creatures shrouded in black robes hurrying by.

Meng Chuan walked slowly, his gaze sweeping over the signs of each shop.

He first entered a rather large medicine shop.

The shop was filled with a faint medicinal fragrance, and rows of jade bottles were neatly stacked on the shelves, labeled with: "Mind-Concentrating Pill", "Enlightenment Powder", "Law Fusion Liquid"...

A waiter dressed in a gray robe approached: "Sir, what would you like to order?"

Meng Chuan glanced at the shelves: "Do you have any pills that can help me comprehend the laws?"

"Yes, yes." The shopkeeper quickly led him to a counter further inside. "This is our best 'Enlightenment Pill.' After taking it, it can bring the user's divine sense closer to the laws of heaven and earth within a month, increasing their comprehension efficiency by more than 30%. It costs ten low-grade divine crystals per pill."

Meng Chuan raised an eyebrow slightly.

Ten low-grade divine crystals for one crystal—this price isn't cheap, but it's not outrageous either.

He just went to the pawnshop and pawned a supreme innate treasure in exchange for twenty high-grade divine crystals.

Divine Crystals are formed from the spiritual energy of the divine realm, similar to spirit stones in the cultivation world.

One high-grade divine crystal can be exchanged for one hundred mid-grade divine crystals or ten thousand low-grade divine crystals.

"Are there any pills that can help fuse the laws?"

The waiter's smile faltered, then he looked troubled: "Sir, you jest. That kind of pill... not to mention our little shop, even on the entire Wanfa Island, I'm afraid you can't find many places that dare to say they can produce it."

"Pills that fuse with the laws of fusion are extremely rare and priceless treasures. They usually only appear at large auctions, and once they are produced, they are fought over by various major powers..."

Meng Chuan nodded calmly, asked no further questions, and turned to leave the medicine shop.

He then visited several other shops and received similar answers.

Although pills that aid in comprehending the laws are expensive, they can always be bought if you are willing to spend the money.

Pills that can help fuse with the laws are truly priceless and unavailable on the market; they can't be found anywhere.

"As expected, the fusion law is the biggest bottleneck."

Meng Chuan understood.

The main reason he was able to integrate the Law of Force, the Law of Slaughter, the Law of Destruction, and the Law of Space so quickly was because the initial stages of integrating the laws were easy, and the "Law of Force" provided assistance.

Even now, with the Law of Power still able to help him, his progress is extremely slow.

After all, what he's about to integrate is the fifth perfect law!

Meng Chuan collected his thoughts and continued walking along the street.

Before long, he saw a fairly large shop with the words "Treasure Pavilion" written on its signboard. People were coming and going at the entrance, and business seemed to be good.

He strolled inside.

The shop displays all sorts of rare and precious medicinal herbs, including emerald green Ganoderma lucidum exuding a rich life force, silver minerals that shimmer with starlight, and colorful flower petals sealed in a crystal box...

Meng Chuan's gaze swept over those rare and precious materials, and suddenly an idea struck him.

He walked to a counter, pointed to a plant inside that was entirely golden and shaped like an ear of wheat, and asked, "What is this?"

The shopkeeper behind the counter glanced at him and replied with a smile, "Sir, you have a good eye. This is 'Golden Ear Grass,' which grows in the golden plains deep within the Divine Realm Continent and contains extremely pure earth elemental power. It is a rare treasure for cultivators who practice the earth element law."

"Does it benefit the internal body?"

A glint flashed in the shopkeeper's eyes as he sized Meng Chuan up and down: "Sir, do you intend to use it to nourish your inner world?"

Meng Chuan did not deny it.

The shopkeeper pondered for a moment, then nodded: "Golden Ear Grass can indeed be used to nourish the inner world, especially for cultivators who have opened up their worlds based on the Earth Element Law. However..."

He then changed the subject, "If a saint has already opened up their inner world, using Golden Ear Grass to nourish that world will only have a... mediocre effect."

"generally?"

Meng Chuan frowned.

"Sir, you are unaware of the following."

The shopkeeper patiently explained, "Although the primordial power contained in the Golden Ear Grass is pure, its total amount is limited. For a saint who has just opened up their inner world and whose world is still very weak, it is indeed of great benefit."

"But once the inner world grows to a certain extent, the original power of the Golden Ear Grass will not be enough."

He pointed to several other rare and precious herbs in the shop, "Like that 'Nine-Leaf Mystic Ginseng' and that piece of 'Star Meteorite Iron,' they can also be used to nourish the inner world, but their effects are similar to those of the Golden Spike Grass, both of which are better than nothing."

Meng Chuan followed his finger and indeed saw several rare and precious materials radiating extraordinary energy.

He stepped forward, sensed each item, and then bought a Golden Spike Grass, a Nine-Leaf Scrophularia, and a small piece of Star Meteorite Iron.

The shopkeeper quickly wrapped it up for him and accepted five mid-grade divine crystals.

Meng Chuan returned to the inn with the three rare and precious herbs. He sat cross-legged in his room, held the Golden Spike Grass in his hand, and used the power of his inner world to refine it.

A warm, golden primal energy surged into the body's inner world, sprinkling down on the earth like spring rain.

however……

Meng Chuan closed his eyes and sensed for a while, then his brows gradually furrowed.

It has some effect, but it's negligible.

After his inner world absorbed this primordial power, there were almost no noticeable changes.

It's like dropping a drop of water into a lake; there's a tiny bit of benefit, but it's negligible.

He then refined the Nine-Leaf Mystic Ginseng and the Star Meteorite Iron, with similar results.

"It just didn't work."

Meng Chuan opened his eyes and gently shook his head.

After ten thousand years of nourishment and expansion, the small world within him has grown to nearly twice its original size.

These ordinary natural treasures no longer have any real effect on it.

Unless one can find even higher-level rare and precious materials, trying to accelerate the growth of one's inner world using this method is nothing short of wishful thinking.

Meng Chuan got up and left the inn again.

Instead of rushing to other places, he wandered aimlessly through the streets, pondering as he went.
